Jesi Roskop has been at St. Luke's for five weeks now. She is expecting her fourth child, and due to complications, she must be regularly monitored and bedridden. Her husband, Doug Roskop, stays at the hospital one night a week and brings the kids, including Milo the mini Daschund, on weekends.

"It makes it feel more like home, it's comforting, you know," said Jesi Roskop. "To me, this is one of my kids."

For anxious and worried patients, dogs are the perfect companions at the hospital. Dr. Angela Gray agrees. "We know that when the body is less stressed, there's less complications in general. And so if an animal can provide decreased stress and happiness, then that would be a bonus for our patients, and us."

Still, patients must get permission to bring their dogs in, and all pups must have recent vet checks and vaccinations. And just like at home, parents must clean up after their pets' messes.
